Engaging the surface of the cam i9 is a pin 2U which is fixed to a'sw'itch point 2l pivotally mounted in the usual manner in connection with the track 22. I provide also a second cam member 23 Which is splined to the shaft 1l by the feather such i 'as 2.4, a spring 25 being provided to throw the member 23 against the pin 20. It will he seen from the drawings that members 19 and :23 have complemental cam surfaces, the hollows in one member being opposite the projections in the other so that acam sot or groove 26 -is formed into which pin 20, projects. It will be obvious also that when the shaft 11 is turned 90 degrees in the manner previously described that the pin Will be shifted in a direction parallel to the axis of the shaft l1, While the switch point 21` will he turned so that the car may be guided in .either direction as desired.
